Abstract
A system to couple light to tissue includes a first light source configured to emit first light of a first wavelength lambda λand a second light source configured to emit second light of a second wavelength λ. The system also includes a retro-modulator configured to receive the first light and the second light. The retro-modulator is configured to modulate the first light of the first wavelength λbased at least in part on an intensity of the second light of the second wavelength λ. The retro-modulator is also configured to reflect the modulated first light for use in generation of a guide-star within the tissue.
